My worst Nightmare ...Lg G4 DEAD ? - G4 Q&A, Help & Troubleshooting

So its Saturday midnight and I m in my buddys house and we were talking and the same time i m on instagram and i scrall around ...when suddenly my G4 freezes and shuts down ...I say wtf and i just power it on (my battery was at around 42)...it starts to boot and suddenly begins to optimize apps ...okkkk i say let it finish ...when the optimization stops and its about to launch my homescreen suddenly blue screen and its powering off...I freaked out!!! i boot into recovery and wiped dalvik and cache...i reboot ....and starts again to optimize the apps ...i say ok everything is good then suddenly it dies again ....i say WTF !!! and i reboot into recovery to wipe everything and do a fresh intall of the Genisys 4.8 rom cause i did a dirty a couple days ago ...as soon as i wipe everything (i have sd and i keep everything there(roms gapps etc...))TWRP freezes and doens do anything after a while it dies again ...I reboot again into recovery to install the rom but when i swipe to flash it just freeze ..i retried it almost 10 times ...nothing it just not gonna do it ...as the time was passing i noticed that the duration between booting itno recovery and freezing was getting smaller and smaller ...so i left my buddys house to go home and flash the kdz (H81520i_00_0927) i put my phone into download mode i open lgup and i do the proper steps (choose the kdz ...closed the lgup ...and reopened it) so i start to refubrish my phone ...when the peosedure was about in 28-30 % my phone died ...I start cursing around ...i put it on the original charger to charge for an hour and a little more ...and i retry ...when the procedure was at 90%(when the phone starts to reboot) without any problems so far ...it starts to reboot but it never boot it just died again ...i pulled out the battery because it was the only way to make sure it was totally closed ...so i power it on and it passes the first lg logo power by android and the unlock bootloader stuff ..and it shows me the android robot with he's stomach working and suddenly it dies again....SO PLZ TELL ME WHATS WRONG WITH MY G4 ?
I want to add some information...
My model never had any bootloops
Its not from the production number with the famous problem
I have dig this particular problem to find if my device was one of them before i unlock the bootloader
For about 3 months i use to charge my g4 through a fast charge cable and though an OEM powerbank
Between a couple of reboots and throught the last time i tried to flash the KDZ my screen flicker the first time was random pixels and the last time it was horizontally the half ....
My first thought was that the battery died ...but when i saw the screen i wasn't sure...
The phone was bought 10 months ago normaly would have 2 months of warranty but with unlocked bootloader thats history ...

Dude, I believe you're having a battery or a hardware issue. Doesn't look like a bad rom installation or anything software related. I'd suggest you take it to LG Support.
Try to successfully pass the original KDZ prior going to LG Support...

i would say bootloop issue.

its the ILAPO issue bro. No more words.

Guys thank you so much for your replies ...I took it to a nearby tech shop that have services for smartphones and the found out that actually its a motherboard problem sometimes its working sometimes not ...we tried a new battery but it dint change anything ....Once again thank you for your replies

I think this is worse than the ILAPO.
I had the ILAPO and now i'm facing this same issue. The unique way to turn it on is putting it on the fridge 10 minutes but it takes 1 min to die again!

What happens when you do a factory reset? Does it load into CWM?
you can access download mode so you can unbrick your phone
I think its not a hardware problem because you can see the lg logo
If you can access cwm menu , wipe user data and cash , then flash hono stock ics.
Then if the phone startup was successful check the hardware parts via hidden menu in stock roms.

Hello,
Guys i did the whole unbricking guide but still when i restart the phone it goes into grey screen when the phone start up even after flashing the stock ICS and the Gb(No i was not able to gain access to CWM). The phone goes into grey screen and wont start up to set the account but if i revome the batter for a few min i can start it back up and go through the google account set up. But after a while if someone called me in the phone i cant hear what they are saying and they can hear me, if i restart is grey screen of death again. :crying::crying::crying::crying:
Thank you drumist for looking into this.
No i was not able to get into CWM. I have to do the unbricking guide to ICS was not able to go to GB as i cant root it goes into grey screen after the phone restarts while rooting causing the root to loose connection with the phone.
Please help.
I have the same problem. This is a problem in the system board. When pressed at a certain point the phone can turn on. I think the problem is contact a BGA chip

Yes this is the exactly the issue i am facing day by day it gets worst. The whole thing started after flashing CM10 ROM. the small bsod you get leads slowly into this. Guys i took real good care of my phone it never fell down from my hand nor does it have a scratch on it. never over did the flashing part as well, my advice is stick with the stock ICS. My Nitro is game over i bough a new Samsung s3. just a word of advice dont over do your beta flashing. :crying:

happyneser how did u resolve the issue.
Please advice i tried every thing in the book and did not pull though.
You need to check the power IC, and make reballing
I was treated to the service (good repair workshop), they said that one of chips was soldered askew.
I think it one of this - Qualcomm PM8901, PM8058 and PM8?7? I do not know exactly.

you might want to retract this statement if this issue is caused by faulty soldering and not CM10

Dear Friend,
i believe i am still right the BSOD now a days Laptop are common mostly HP, its Due to the VGA chip being BGA(ball grid array) they are chips with small balls with soldering underneath them used for comm between the chip and the Bord. but went to chip overheats it melts the solder underneath and when it cools back down the solder get solid it a different area(we moving the phone like taking out of pocket or so) which causes lack of communication between chip and board(when they are back solid) it causes BSOD. I believe the Graphic chip in NITRO HD is using the BGA tech(It makes sense) so if our phone overheats too much the chances of De-aligning the solder in the chip is high cousin BSOD. We all know CM10 at the early stages caused overheating while in black screen coursing huge power drain in battery(we have stigmatic data with the help of battery analyst app).
So summer Nitro HD = BGA , CM10= overheating, Overheating=Bad for BGA(Causes BSOD) so overheating Nitro HD causes BSOD there u have it. i case if the phone really overheats while its in your pocket of in a uneven place and the solder goes out of place then you are in trouble like me.
Solution= Re balling or heat gun(temporary) Can FIX it.
So it's pm8028 near mdm9200
I got the same problem last weekend. I woke up and found the screen on and no sound from alarm clock. I checked and the phone got no sound at all.
I restarted the phone and got the gray screen. Late at the day the phone boot again but after another reboot it got the gray screen and never recovered.
I use CM10.1 and wind kernel with no overclock.
Too bad I didn't find any shop that reball the chips so my phone is dead
I got a i9305 today to replace it.
cn you fix the re-ball?

Can you enter recovery mode? If yes, do full wipe then flash your ROM.

Make sure the phone is fully charged before you try to boot it up, if it is fading out after the logo splash screen it either sounds like a dead battery or a badly flashed rom. You can enter into recovery by holding the volume down and pressing and holding the power button till you get prompted to wipe the phone.
I have had a couple of grey screens (or "black" screens) which I was able to recover from, simply by making sure the phone was powered off, then fully charging the battery for 4 hours, then booting into recovery and flashing a different ROM

ok... will attempt to reload
will try and download and attempt .....

[Q] LG G3 Turning Off Problem

I have randomly started experiencing a problem where my device would turn off randomly which has gradually gotten worse to the point where it's stuck in a boot loop sort thing and will shut off randomly during boot then restart.
The problem started by every now and then (sometimes not happening for a day at a time) the phone would turn off then turn back on again gradually getting worse. The problem started when I installed the latest update during the update the screen froze (no it was not interrupted in anyway and done officially through the phone) so after leaving it overnight and it not progressing I took the chance and removed the battery. it then turned on and finished the update without an issue. The phone has since as I explained got into a 'boot loop' sort scenario where it will work if the charger is plugged in but couldn't be a battery issue as doesn't turn off if I put it into download mode. Things I've tried: Doing a complete reset- Still no fix. and now today I entered download mode and re-installed the firmware which was successful but still no prevail?! What the hell could this be?! Thanks

Maybe it's a hardware issue
hi, where did you get the firmware? it could be corrupted. if I were you I would download again the firmware and reflash it.
after that I'll do a hard reset.

Well i guess im not alone as i have the same exact problem as you do! WHich version do you have? I have the White T-Mobile version and i bought it the same week it was on sale i felt that i got a phone that was part of a bad batch because of some problems ive had with it but i didnt buy insurance for it. i was on LG's OS and it started to get worse and worse so i restored it and went to a lollipop rom. its still happening but it only reboots once. however, as soon as i start using apps it reboots on me. i want to unroot it but at the same time i dont want to go through the trouble of rooting it again. Any ideas of what it could be?
My problem just randomly started happening and i noticed this started happening strangely after my phone completely died on me and didnt want to turn on so i connected it to the charger and it started charging but had a yellow warning triangle somewhere on the screen.

Hey, nice to hear someone has the same issue, I however hvent had the yellow warning triangle come up yet, as an update all of a sudden it keeps turning off as soon as it boots even on charge!!!??? It just keeps getting gradually worse?! However I have noticed the battery % it shows when turned off is 100% and very randomly it displays 70% then when the phone boots it will show 2% for the 2 seconds it stays on before it dies?!

Wait now it reboots on you even if its charging? I too started noticing that with my battery . if I turn it off and charge it it and lets say it says its at 75% well I turn it on and its like at 40%? I really don't want to buy another battery but I actually hope the battery is the culprit. There's a guy with a G3 in my school I'm going to see if he let's me try his battery out on my phone I'll keep you posted

Hey sorry for taking so damn long on replying i've been busy studying for some exams.
I've got good news for you though, i took my phone in to T-Mobile and showed them my problem. Without me putting much effort into persuading them, they shipped me a new phone, and no i didn't pay for insurance on T-Mobile, this was covered by LG's 1 year Manufacturers warranty!
Anyways, I received the device but did not receive a battery. So i tried my battery on the new one and what do you know? SAME PROBLEM!
So yea you should either try to unroot the phone and take it to the store but don't mention that you think its the battery, they'll send you a new phone! Then just buy a battery online or call them after a few days and say your problem is still occurring with the new phone and see if they send you a replacement battery, im a little skeptical on this second option as id rather keep this new phone haha

Hi, even i am having this problem, my phone is a D855 and in my country (Mozambique) i am not using a contract so its different than US, we have a LG store here but in the LG website our country is not stated. So only way is to go to a trusted Store that repairs phone here. My question is that, when its not connected in the charger it just keeps reboting (the notification LED doesnt even blink) infinite times. At first i thought it was a software but after going from Stock to Cloudy to CandyRom the problem was still there. Then after i plugged in a charger the phone would succesfully boot up and i could use it normally but had to stay connected on a charger. So what have you done to fix this? Did you replace the battery with a new one and then it stopped rebooting?? Please help me as i want to buy a new battery but first want to confirm if its the battery at fault....

Hello buddy, sorry for taking so long to reply. Im usually not on XDA too much. Yes i solved my issue with a new battery. I tried my bad battery on 2 lg g3s and it rebooted both. I also unrooted my phone and flashed a completely stock update and was still having that issue.
I hope my response isnt too late for you!
No problem bro! Got a new battery and do far my phone doesnt reboot, but the only problem i am having is that my phone shutsdown at 30% battery and when trying to turn on it says it has 0%

Im having the same problem gotba new battery and no different so annoying
Best thing just happened. I had the G3 for a while and my first one had an issue and had to get a warranty replacement. Long story short... I got two more G3s from T-Mobile that were defective and most carries have a policy where if you get 3 warranty replacements you can chose a different phone. To wrap it up, you can ask for a phone of equal or lesser value when purchased from the carrier (I bought mine off eBay and they didn't even notice, I spoke to several reps and no one caught on.) So they can either send you a whole new phone, a new battery, or in my case: I received a new LG G4 since I had gone through three which pretty much anyone can do with a bad battery.
Guys. Im having this same exact problem on my LGG3!!!
Expired Battery or Faulty Power Button could be the culprit
This issue just started happening to my LG G3 over the last 2 weeks. I've had my LG G3 for exactly 15 months and all of a sudden it started cycling endlessly and if it did get to my locked screen and i tried to unlock it it would just restart again.
I found that when I plugged in the device to a wall charger or high power power brick, it would halt the reboots but otherwise it would get stuck in an endless cycle of partial reboots (when it did stop after plugging in, I would find all my apps still open and waiting for me, so they weren't real power cycles).
One of my coworkers has a newer LG G3, so we swapped batteries and immediately he had the cycling issue on his phone and with his battery in my phone the issue vanished.
On closer inspection, my battery was a few months past its expiration (FYI to anyone with a LG G3 - your battery will expire more or less exactly as its warranty protection does!), so went and bought a new battery and everything is fine now.
For those of you who have tried replacing the battery and find it still occurs, another coworker said his wife had a similar issue on a different device and it was resolved by having the power button replaced, so it is possible that this could be a factor also and you should have your phone sent in for inspection/repair.
Hope this is helpful for some of you.

I've had the same issue since February, when my phone was about 17 months old. It kept turning off saying SIM card not detected. I tried replacing the SIM card and washing that area with alcohol with no luck. Then I replaced the battery with a second one that came with the phone which I'd never used, but I noticed no difference. It also has no phone service for several hours without my knowledge. LG just told me to reset the phone, but it looks like that doesn't work from what I've read. T-Mobile said they'd give me a new phone but there are no G3s in stock and offered me a Samsung 3, which is three years old, so I am worried that it won't be able to handle the software updates. It's ridiculous that a phone that costs this much won't even last long enough for me to pay it off. My last phone was an Iphone, which I had for more than four years.
I had the exact same problem a few weeks ago, posted a detailed explanation of the problem and got 0 replies and a few hundred views (thanks guys!)
Easy answer:
Replace your battery
Thats what I did, and the problem is now gone. When you do get a new battery make sure you drain it completely first, then charge it for 4 hours without exceptions.
I tried factory resetting, installing a new firmware, going to stock and going to custom but nothing worked.
The girl in the shop where i bought the battery surprised me, i just asked her if they had one available and her immediate reply way "why, is your g3 stuck in a boot loop?", apparently EVERY SINGLE PERSON that bought a g3 battery from them had the exact same issue.
Now the problem is gone, and my phone actually lasts longer than before.

Hey, I am having the EXACT same issue. LG G3 was stuck in an endless loop, replaced the battery, now it works down to about 30% and shuts off. When I try to restart it says 0%. I even tried a third different battery, and still getting that 30% shutdown. Did you ever figure out what it was? I am wondering is it something to do with how the phone reads the battery charge i.e. does it think the battery is dead when it gets to 30%? It has e stumped!! Any advice would be most welcome. Thanks.
wtf,actually same with my LG G3,after when I bought a new battery. Shutsdown at 30% and it says has 0%.
same problem

I HAVE THE SAME PROBLEM help PLEAAAAASE

Faulty battery that wasn't faulty for 8 months?

Okay I recently wrote a thread about the random restrarts on my g3 that happened 10 times a day, but the things have gone too far. As i was having random restarts when I monstly use the camera but not only for about 5 days and some of those restarts were also shutdowns now the problem is more serious. Today i was intending to take a picture of something and as usual the phone restarted but STUCK on the startup boot "picture" that says that lifes good and then goes black screen and startup picture and black screen and so on. I wasn't able to use the phone. I pulled out the battery and tried again but it didn't worked. So as I went home i plugged the phone ot the charger and when i powered it on it started normally and tried to take pictures and there weren't any problems. So I think that this is the battery that is making this **** to happen. I highly doubt that this is software problem but from my quick examination i think that the problem is from the battery . What do You think. Tommorow i will go to my carrier and "ll try to explain them about this. But they are usually jerks who don't know anything about phones. They only know how to get your money.Anyways. Yes.

Are you rooted? Did you flash anything? Did you edit any system files? Looks exactly like when I bricked my phone. There is a fix. Check out this thread and the links in it. http://forum.xda-developers.com/lg-g3/help/lg-g3-unbricking-steps-clarification-t3119844
Also can you access download mode or recovery. You might want to try them first.
No I havent rooted it or made any system modifications. This problem occurs only when my phone isnt charging. When iits charging even at 100% there isnt any problem
I've gone to my stupid carriers office and explained everything but they do not want to give me a new battery unless they bring the phone to the other end of the country for repair. This is extremely stupid. Now I can't use my phone because its totally "bricked". I xan only use it with my original dc charger if i unplug it the phone shuts off. Yesterday Ive decided to make a factory reset, but i wanted to copy my internal storage to my pc, but the phone won't turn on when its plugged to the pc. I don't know what the **** is happening with this 500 piece of pancake.
well i have finally decided to do a factory reset but after the anticipation and thinking it is a software problem it isn't apparently. Maybe i will just send it to repair and hope that i wait less than 20 days for it to come back. And i hope that they don't figure out the problem and send a new phone but i think it is the battery that is the problem. Anyways the modern technologys are the most incredible thing and the most getting you pissed of one. You pay 500 dollars+ and expect something good and there you go .
So did you do factory reset or not?
Btw, getting phone to repair center is a good decision, they'll see what's wrong.
I have been happy with my G3, only "minor" thing I don't like is the horrible backspeaker (coming from HTC One m7)

LG G4 H818P Bricked/Dead While using

Dear All,
A friend have LG G4 H818P the Dual SIM variant, While he was using Facebook the device suddenly turned off, tried to charge it with no hope, can't enter download mode or hard reset
He gave it to me for a try, i try the old thing with wrapping the phone in a piece of cloth and left it in freezer for 30 minutes - don't laugh - plugged the battery and the phone is working !!! started with LG logo with no successful boot to main screens just LG Logo.
Once the phone isn't a freeze cold it wouldn't turn on !! which is very strange , every time i leave it in freezer for 15 minutes or less it works !!
Will try now to enter the hard reset and do it, also downloading it's latest KDZ and will try to flash it but any idea what's happening and how can i solve it ??
Thank You

I have a h815 lg g4 32 gb. Running on MM. I had the same problem with my device today. I couldn't solve it. All i want is save my data. Windows os not recognized my device. QHSUSB_BLUNK. I guess it's brick. I don't know it's soft or hard brick. I guess i can save my data on linux os or fix the problem on it. Any idea?

seems like infamous bootloop.. if under warranty send it to LG but it must be to the corresponding country it belongs. like if am in america then i have h815 usa wont fix it i have to send it to europe.
or replace motherboard yourself
Unfortunately it's not under warranty, he had it for a year and 4 months
So no one was able to fix this at all ?? it's very annoying !

why not give it a try.. they might fix it.. as it is a hardware problem that many devices are suffering.
Same here
Ok so I have the lg g4 h811 2nd variant after getting the original replaced by lg because of infamous boot loop problem, get the one that was redesigned to negate that error. So this Phone dies while watching YouTube and tried freezing it, discharging the capacitor, new battery the whole 9 yards. No go. New problem maybe? Touched a multimeter to all possible problem areas and it looks like the whole thing shorted out from top of board to bottom all at once because it read max resistance. The whole thing is dead unless someone has an idea to revive it?
same problem
i have the same problem here
waiting for some help

Pop out battery
Take out screws
Don't bother with camera screws
Pry plastic
You will now see the motherboard
Get a blow dryer
Heat this part for 5 minute full blast
Do not touch actual chip.. But do get pretty close
Put cover and screws battery back in
Power up
If she bootloops again....heat it again
ops

Google Nexus 5X LG-H791 Bootstuck

Hi,
I got an issue last night with my Nexus 5X, he suddenly stopped without the possibility of restarting it.
The battery was 80% full and i never installed any rom on the phone.
It's not a bootloop because when i press power, google screen appears for 5-10 seconds then the phone shutdown again.
I tried to press power + volume -, but no option in the menu works.
I don't know what to do but to get in contact with the seller to make the warranty works, i get pissed for all the data on it :'(
Sorry for my bad english, it's not my mother tongue :crying:
Same issue

I am having the same issue as you, I even managed to flash the stock 7.1.2 and it worked for 10 minutes then it froze and went back to not working at all.
I have no idea how to fix this and I am out of warranty.
i got issue 15 minutes ago too, dont know why it stopped.
i suffing web and suddenly it turn off screen.
i do all thing i can but nothing work:crying::crying:
my devices is Google nexus LG H790
Mine died on me a couple months ago in this same way. I do believe this is the bootloop or hardware failure that is known for the LG phones at the time. The V10, G4 and Nexus 5X have all been effected by it. When it happened I did some searching online and saw a video of someone putting it in the freezer for a short time to cool the motherboard and it turned on for a limited time. It was long enough for me to back up the stuff I need before it shut off again. I was also able to wipe and factory reset it another time the same way. It's been harder to get it to turn on lately. A better fix I saw (although temporary as well) was taking the motherboard out and using a heat gun to reconnect the solder. That is what I believe the issue is. But I haven't gone that route.
oh my.. it happened to me yesterday, now i see this... i flashed a new recovery and nothing, it passes the google screen to black.
Ill try the freezer thing to see what happens
Hello,
Thank you all for your answers & testimony ^^ , how long did you put it in the freezer?
This manipulation can kill the warranty ?

i had it like 20 miutes and it worked a few minutes, now im trying longer...
as for the warranty, i dont think it has anything to do... its like when u go to the mountains or if u live i a really cold country :lol:
This is how my phone acted before it eventually boot looped. Letting it sit in the freezer for a while would get it to go into the recovery menu, but it would not enter recovery or boot. The only way I got it to actually boot was using a hair dryer on the motherboard. But it immediately froze once unlocked. It also bootlooped. I got it to boot for a long period only by using a heat gun on the motherboard. Second time around I used a higher setting and it acted normal for 9 hours. But then it rebooted on its own and eventually bootlooped again.
A video In Spanish, but good walk through and you can just follow the video with subtitles.

I only put it in there for maybe 5 to 10 minutes. The longer it's in there the more condensation builds up on it. This is the video I watched that gave me the idea. He talks about it in the beginning. So I just tried it.

EDIT: I see the post above me has the same video.
